Description
Technical field
The present invention relates to a kind of square cabin lifting device, more particularly to a kind of snail formula elevating mechanism and system.
Background technology
The structure of shelter is similar to container, is generally welded by sheet metal, and shelter is generally equipped with carrying car, one
As be picking-up vehicle, delivered by carrying car to required place, its standard be also refer to container standard formulation, with container
Compare, shelter has higher mobility, can be field rescue using the various articles of the space configuration of shelter and equipment
Reliable guarantee is provided Deng action, as shelter is in the extensive use in the fields such as emergency management and rescue, fire-fighting, communication, military affairs, the liter of shelter
Drop is using and is seeming particularly significant in transport process.
The shelter heavier-weight of equipment and object is equipped with, to realize the loading of shelter to picking-up vehicle or unload, generally
Use and set lowering or hoisting gear to be supported and lift shelter respectively on four angles of shelter, traditional lowering or hoisting gear is needed
Want four people simultaneously hand at four angles of shelter, it is time-consuming and laborious, it is more difficult to realize that shelter corner is lifted simultaneously, there is object damage
Bad and security risk.
And with the development of modern technologies, a kind of electronic square cabin lifting device is developed, the square cabin lifting device is provided with
Two supporting legs, wherein a ground connection supporting leg that ground is stood on for supporting leg（Including inner sleeve and outer tube）, another is and shelter
Fixed shelter bearing, and set connection pole to connect two supporting legs, using chain is by shelter bearing and is grounded supporting leg
Connection, motor drive driving wheel rotation, chain install on the drive wheel, chain-driving inner sleeve stretched out in outer tube or
Withdraw, outer tube and shelter bearing synchronously rise or fall, realize the descending operation of shelter.
But there is problems with this electronic lowering or hoisting gear：1st, efficiency is low, lifting time is longer for lifting；2nd, lift heavier
Shelter when, it is necessary to the motor torque demands being equipped with are high, and heavier shelter after target location is elevated to because of self gravitation, side
There is downward impulse force and swing or jiggly situation in cabin；3rd, it cannot be used under no supply of electric power state, be shelter liter
Drop operation is made troubles.
Therefore, it is necessary to be improved to existing square cabin lifting device, to be more suitable for quick field rescue
Deng the use demand of action.
The content of the invention
It is an object of the invention to overcome in existing square cabin lifting device, purely manual lowering or hoisting gear is wasted time and energy and deposited
In security risk, and Motorized lift device is low, high to motor torque demands in the presence of lifting efficiency, and when shelter deadweight is larger,
Shelter exist impulse force swing or the technical problem of jiggly situation there is provided a kind of snail formula elevating mechanism and system, the lift
Structure provides larger driving torque by the conversion of worm reducer, reduces the torque demand of drive device, and utilizes worm gear snail
The self-locking property of bar makes shelter lift steady, safe operation quickly, is adapted to the use of the action such as quick field rescue
Demand.
In order to realize foregoing invention purpose, the invention provides following technical scheme：
A kind of snail formula elevating mechanism, including the driving wheel and drive device being equipped with driving-chain, are filled in driving wheel with driving
Worm type of reduction gearing is equipped between putting, when drive device drives driving wheel rotation, drive of the shelter bearing in driving-chain
It is lower to be lifted.
The elevating mechanism arranges worm type of reduction gearing, can be by the torque of drive device using the big speed ratio of decelerator
It is converted into larger output torque and is supplied to driving wheel and driving-chain, improves lifting efficiency, reduce to drive device moment of torsion itself
Requirement, save drive device type selecting cost, be adapted to heavier-weight shelter lifting；In addition, utilizing the self-locking of worm and gear
Performance, after shelter is being elevated to target location, prevents that shelter from swinging because of the impulse force that self gravitation is brought, makes shelter lifting flat
Surely, safe operation is quick, is adapted to the use demand of the action such as quick field rescue.
